This invention relates to improvements in miningmachinery and has particular reference to a machme for usefwlthln a mlne for the purpose of trappingthe falling ore or muck.

The prlncipal objectof this invention is to produce a trap which will prevent the material being blasted from spreading any great distance fromthe surface being loblasted and to further provide a device wherein the various implements employed for removing the blasted material may be brought up and cooperate with the trap in such amanner as to receive the blasted material and to convey it to. a distant point.

i Another object of the invention is to produce a device wherein a large percentage of the blasted material maybe elevated and dumped into a hopper from which hopper the material may be discharged to a conveyor. v

Another object is to produce a device which is simple in construction and one which will not be injured tllrough the pounding of the flying material incident to i the explosion.

V A further object is to produce a device which may be so'adjusted that it will accommodate itself to tunnels or drifts of 150. various widths and heights. v

A still further object is to produce a device of this character which is economical to manufacture.

Other objects and parent during the following description.

V In the accompanying drawings forming a part of this specification and in which like advantages will be apnumerals are employed to designate like parts throughout the same, 40,:

and Figure III is a rear elevation of Figure I. In mining it is common to drill holes into 45. the face of the drift into which holeseX- "plosive is placed. This .explosive'is fired with the result that theface of the drift is shattered and considerable'rockior'muck is dropped onto the floor of the drift. It has 50. been common to transport the material away Figure I'is a side elevatlonof my devicep Figure II 15. a top plan view of Figure I;

Applicant has provided a device which will catchand elevate most of the. material into ahopper in a very simple manner.

In the accompanying drawings wherein for the purpose of illustration is shown a. preferred embodiment of my invention, the" numerals 5; and G refer to tracks: laid upon the customary ties 7 upon'the floor of the drift. It is .uponthese rails that I place my device which consists essentially of. 'a

primary hopper 8 which hopper has an 7 opening 9 in its-bottom for the purpose of discharging material within the hopper to a conveyor placed thereunder. This hopper 8 is mounted upon wheels 11 and 12. By referring to Figure III it noted that the rear wheels are upon separate axles thereby leaving a space therebes. tweenfontheforiveyor to pass [under the hopper. Thishopper 8 has a frame supported thereon, which frame may be of any standardshape here shown as four posts designated. at r 13, 14, '16 and 17. Braces 18 are provided, the purpose of which isobvious. Hinge dly secured to the'hopp'er '8 ar baflle plates 'asshown at 19, 21 andf22.

These fle'pl'aas have secured thereto ca:

'bles 23 which cables pass through eyesgin the uprights13 and 14: and are joined to a common pullingcable 2 1 which'cablepass'es to a drum 2 6'which may be'rotated any convenient manner. I

In order to prevent the flying of material beyond the rear extremity of the'hopper I provide a baffle whichc'onsists of a central section made up of vertically adjustable plate 29. These three 1 plates are elevated through the medium-of screws 31 and 32.

plates 27 and: 28-and acentrally removable Auxiliary ibafile plates j are .shown at and i 3Afwhich1are movable through-the medium;

Q QF S36IZLH1 .37 espe v y- Th re-- sult 'ofthis construction is that; when \my device is placed withina mine drift as shown inthenfigures and-an explosion IS'SG'G off,ff

the falling} material will -be confined be tween the face of the drift the baflle'atthe rear thereof. The inclined bafl leplate 19, 21 and 22 will also catch a large portion of the material with the result that these bafiles may be elevated through the medium of the winding mechanism 26 and may be elevated either independently or collectively, depending entirely upon the arrangement of the to s. When these bafiles have been elevated t ey will assume the position shown in dotted lines of Figure I with the result that the primary hopper will have an auxiliary hopper formed on the top thereof. B removing the bafiie plate 29 the boom of a drag sweep may be extended over the hopper and with the baffle 21 in lower position loose material may be scraped up and dumpedin the hopper. W'hen the hopper is filled, a conveyor may be positioned underneath the same and receive material thereon. It will thus be seen that I have produced a device which will effectively trap flying material and one wherein material may be readily elevated into a hopper for further treatment.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement-of arts may be resorted to without departing rom the spirit of the invention or the scope of the sub oined claims.

Having thus described my invention, I claim 1. In a device of the character described, a hopper, a plurality of baflles pivotally secured to said hopper and extending downwardly and outwardly therefrom in such a manner as to form an apron about said hopper, a framework supported on said hopper,

means carried by said framework for elevating said baflies, and a vertically disposed bafle secured to said hopper and in the rear thereof for the purpose specified.

2. In a device of the character described, a hopper, a plurality of ballles pivotally secured to said hopper and extending down- Wardly and outwardly therefrom in such a manner as to form an apron about said hop per, a framework supported on said hopper,

means carried by said framework for elevatingsaid bafiles, a vertically disposed bafile secured to said hopper and in the rear thereof, said vertically disposed baflle comprising a plurality'of plates. 7

3. In a device of the character described, a hopper, a plurality of bafiies pivotally se cured to said hopper and extending downwardly and outwardly therefrom in such a manner as to form an apron about said hopper, a framework supported on said hopper, means carried by said framework for elevating said battles, a vertically disposed baflie secured to said hopper and in the rear thereof, said vertically disposed baffle com prising a plurality of plates, and means for adjusting said plates transversely.

4. In a device of the character described, a hopper, a plurality of battles pivotally secured to said hopper and extending downwardly and outwardly therefrom in such a manner as to form an apron about said hopper, a framework supported on said hopper, means carried by said framework for elevating said battles, a vertically disposed baflle secured to said hopper and in the rear thereof, said vertically disposed baflie comprising a plurality of plates, means for adjusting said plates transversely, and means for elevating said plates for the purpose specified.

In testimony whereof I aflix my signature.
